Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
config router interface > edit port1 > set address [IP] > end
Why it's wrong here
Incorrect. Interfaces are configured under system interface, not router interface.
- ✓
config system interface > edit port1 > set ip [IP] [netmask] > end
Why this is correct
Correct. This sequence navigates to the interface context, modifies the IP address, and saves the changes.
- ✗
set interface port1 ip [IP] > save
Why it's wrong here
Incorrect. This command syntax is invalid for FortiOS.
- ✗
execute set ip port1 [IP]
Why it's wrong here
Incorrect. Execute commands do not modify persistent interface configurations.
